  • Patent number: 11896389
    Abstract: A paralysis monitoring system can be utilized during various medical procedures. Generally, the system is used during procedures involving anesthesia, when general paralysis is necessary, e.g., during surgery that requires cutting through or mobilizing muscle tissue. The paralysis monitoring system stimulates a nerve with low voltage signals and can provide for continuous monitoring and recording of the evoked muscle activity throughout and after a procedure. By monitoring a quantitative response of the muscle activity to nerve stimulation, an anesthesiologist may adjust subsequent doses of a paralytic agent to achieve a desired level of paralysis.

  • Patent number: 11751929
    Abstract: A surgical instrument is disclosed that comprises a motor, a radio frequency (RF) energy generator, a first jaw, a second jaw movable relative to said first jaw in response to an actuation from said motor to capture tissue, and a segmented circuit comprising a first electrode configured to measure tissue impedance at a first position and a second electrode configured to measure tissue impedance at a second position. The RF energy generator is configured to transmit RF energy to the tissue by way of said first electrode or said second electrode. A controller is configured to control said motor based on the measured tissue impedances, energize said first electrode with a first amount of RF energy based on the tissue impedance measured at said first position, and energize said second electrode with a second amount of RF energy based on the tissue impedance measured at said second position.

  • Patent number: 11737918
    Abstract: A device is described herein for performing capsulotomies that improves suction uniformity and produces rolled capsulotomy edges. The device includes a suction cup that forms a tapered circumferential suction chamber which enables suction to be applied to a tissue in a first direction. The tapered circumferential suction chamber decreases in cross-sectional area from a proximal end of the device towards a distal end of the device. The device further includes a stem coupled to the suction cup to provide suction to the suction cup. The stem forms a neck that enables fluid flow to the suction cup in a direction substantially perpendicular to the first direction. The device further includes a cutting element configured to excise the tissue.

  • Patent number: 11737809
    Abstract: The disclosed technology is directed to a surgical instrument comprises a sheath having respective opposed proximal and distal ends. A pair of grasps is disposed on the distal-end portion of the sheath gripping a treatment target therebetween. A drive shaft is coupled to at least one of the pair of grasps to open or to close the pair of grasps by being moved along the longitudinal axis with respect to the sheath. Electric elements are used to apply treatment energy to the treatment target. A first operating device supplies the electric energy to the electric elements in a first supply state. A first member produces a force to open or close the pair of grasps and applies the force to the drive shaft. A second member is disposed in line with the first member and applies a force to the drive shaft in response to the operation input.

  • Patent number: 11723684
    Abstract: An apparatus includes a body assembly, a shaft defining a longitudinal axis extending from the body assembly, an acoustic waveguide having a flexible portion, and an articulation section coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section has a first member and a second member translatable relative to the first member. An end effector has an ultrasonic blade that is in communication with the waveguide. An articulating control assembly has a motor. The motor is operable to translate the first and second members to thereby deflect the end effector away from the longitudinal axis at the articulation section.

  • Patent number: 11672591
    Abstract: Unintended current flow or plasma discharge has been observed in known illuminated electrosurgical devices having a metallic tubular heat sink surrounding a conductive electrode and an illumination element, and having a distal outer edge that abuts against the light emitting element. An insulating, shielding or other isolating element that prevents or discourages unintended plasma formation between the distal outer edge and nearby patient tissue can reduce the potential for tissue damage to a patient or injury to a surgeon.
